Creator:: Hales, Burke, Moum, James N., Covert, P., and Perlin, A.
Abstract:: Detailed and repeated measurements of nitrate across the Oregon shelf, made coincident with turbulence measurements, reveal the importance of cross-isopycnal mixing via turbulence in providing nitrate to the upper water column. Spatial distributions of vertical gradients and turbulent fluxes in the Oregon coastal ocean reveal variability that could not have...

Creator:: Avicola, G. S., Moum, James N., Perlin, A., and Levine, Murray D.
Abstract:: The upwelling-driven coastal jet off Oregon is in geostrophic balance to first order. The accompanying thermal wind shear is stable to shear instability. Yet enhanced turbulence is observed in the upwelling jet, typically as long, thin patches with horizontal to vertical aspect ratios of 10² to 10³ (median value ~300)....

Creator:: Moum, J. N., Perlin, A., Klymak, J. M., Levine, M. D., Boyd, Timothy John, 1958-2013, and Kosro, P. M.
Abstract:: Closely spaced vertical profiles through the bottom boundary layer over a sloping continental shelf during relaxation from coastal upwelling reveal structure that is consistent with convectively driven mixing. Parcels of fluid were observed adjacent to the bottom that were warm (by several millikelvin) relative to fluid immediately above. On average,...

Abstract:: Near the bottom, the velocity profile in the bottom boundary layer over the continental shelf exhibits a characteristic law-of-the-wall that is consistent with local estimates of friction velocity from near-bottom turbulence measurements. Farther from the bottom, the velocity profile exhibits a deviation from the law-of-the-wall. Here the velocity gradient continues...

Creator:: Hales, Burke, Karp-Boss, Lee, Perlin, Alexander, and Wheeler, Patricia A.
Abstract:: We examined high-resolution cross-shelf distributions of particulate organic carbon (POC) and dissolved O₂ during the upwelling season off the Oregon coast. Oxygen concentrations were supersaturated in surface waters, and hypoxic in near-bottom waters, with greatly expanded hypoxic conditions late in the season. Simplified time-dependent mass balances on cross-shelf integrated concentrations...

Abstract:: A pair of hydrographic sections, one north and one south of Cape Blanco at 42.9N, was sampled in five summers (1998–2000 and 2002–2003). The NH line at 44.6N lies about 130 km south of the Columbia River, and spans a relatively wide shelf off Newport, Oregon. The CR line at...
